A subject undergоes а twо-pоint discriminаtion test: Body Region Distаnce Detected (mm) Fingertip 2 mm Palm 10 mm Forearm 20 mm Additionally, a coin placed on the forearm is no longer felt after 45 seconds. Instructions:1. Trend Analysis (2 pts) Describe how sensitivity varies across body regions. 2. Interpretation (2 pts) Which region has the highest receptor density? Justify. 3. Comparative Reasoning (2 pts) Explain how receptive field size differs between fingertip and forearm. 4. Physiological Explanation (4 pts) a. Explain sensory adaptation observed in the coin test.b. Predict how results would differ in a patient with nerve damage.
